How to point JavaScript to elements

This we also know, through CSS selectors. They are the ones we have learned about in “Adding colour” . What we need to do is write document.querySelector(“#first_leaf”) . This points to the first leaf. Sadly, this bit of JS code will not do much except allowing us to access the first_lead element.

If we want to select all the elements that fall under a certain selector there is document.querySelectorAll(“”).

Tomorrow we will learn about functions because we will need them in order to play with our elements.
